Many inborn errors of metabolism are characterized by a change in the amount of glucose and ketone bodies in the bloodstream. Two of these disorders affect liver enzymes; Carnitine palmitoyl transferase deficiency and glycogen synthase deficiency. Both disorders lead to hypoglycemia but only one is also associated with hypoketotic hypoglycemia. Explain why both disorders lead to hypoglycemia and which disorder would also result in reduced ketone body synthesis.

Which of the following metabolic changes will occur in a typical human after a meal balanced in carbohydrates, protein, and fat is consumed? (Select ALL that apply!) Liver glycogen synthesis increases Muscle glycogenolysis (glycogen breakdown) increases Liver gluconeogenesis decreases Insulin levels in the blood decrease Ketone body production in the liver is increased ..... Which of the following metabolic changes will occur in a typical human during 12 hours of fasting? (Select ALL that apply.) Liver glycogen synthesis decreases Liver...
26. Why did Jessie’s carnitine deficiency cause her to have abnormally low plasma glucose levels at the end of a fasting study, when compared to a healthy person who has fasted for the same length of time? In the absence of carnitine, the liver stores large amounts of glycogen; absorption of glucose to create these stores depletes blood glucose Carnitine acts as a hormone and stimulates glucose release from the liver; lack of carnitine results in loss of hepatic glucose...
Deficiencies of carnitine, carnitine acyltransferases, or carnitine/acylcarnitine translocase affect the metabolism of long-chain fatty acids. Many of the symptoms are similar, and include hypoketotic hypoglycemia (low ketone levels and low blood sugar with fasting), and damage to the liver, heart, or muscles due to fatty acid buildup in those tissues. Symptom severity varies with the form of the deficiency.
The following abbreviations are used: carnitine acyltransferase (carnitine palmitoyltransferase), CPT and carnitine/acyl carnitine translocase, CACT.
Identify each symptom or effect as...
Investigate short-chain (12 carbons or less) fatty acid metabolism: Monitor ketone body formation in the blood Results: Interestingly, when Jessie was fed a solution containing short-chain fatty acids and again fasted, plasma acetoacetate and γ-hydroxybutyrate concentrations increased. 15. What does this result tell you about Jessie? A. Nothing B. Something, but not clear what C. One of the enzymes of the β-oxidation pathway must be deficient D. There must be a problem with specifically long-chain fatty acid transport, not with...
1. What is happening in a healthy individual about an hour into a glucose tolerance test? (Note: At this early time-point, blood glucose levels are still high. Also, remember that a person who is taking a glucose tolerance test was fasting for 12 hours prior to the test!) (Select ALL that apply!) Hint: Review pages 319-325, 462-467 and 489-491 of Tymoczko 3E before attempting this question. A. Glucose is being exported by the liver B. Glucose is being taken up...

Hi the automatic grader for my biochemistry assignment is saying
im getting things wrong but i cannot figure out which. Please tell
me which are wrong with corrected answers. Thanks!
Which of the following is true regarding glycogen metabolism? O Glycogen synthase is activated by phosporylation. Glycogen phosphorylase kinase activates glycogen phosphorylase through phosphorylation. The activation of PKA is downstream of insulin signaling in muscle cells. O Glycogen phosphorylase releases free glucose from the ends of glycogen Question 7 (2.5...
